Taiwan Semiconductor Corporation GP1601H

Overview

GP1601H from Taiwan Semiconductor is a 16A, 50V AEC-Q101-qualified standard rectifier diode in TO-220AB package with dual-die configuration, 1.1V max forward voltage at 8A/25°C, 150A surge rating, and 1.5°C/W junction-to-case thermal resistance - used in automotive-grade DC-DC converters and switching inverters.

For engineers reviewing the GP1601H datasheet, GP1601H pinout, GP1601H application, or GP1601H equivalent, key selection criteria include repetitive peak reverse voltage (50 V), AEC-Q101 qualification status, TO-220AB mechanical compatibility, thermal performance under high-current conduction, and compliance with halogen-free and RoHS requirements.

Technical Context

This device is a single-phase, dual-die standard recovery rectifier optimized for high-current, medium-voltage power conversion. Its 150A non-repetitive surge capability supports transient load handling in switching mode power supplies, while the 1.5°C/W R_θJC enables efficient heat transfer to heatsinks in constrained automotive and industrial enclosures.

The GP1601H operates across -55°C to +150°C junction temperature range and exhibits 10 µA max reverse leakage at 25°C and 250 µA at 125°C, supporting stable operation in thermally demanding environments without derating below 16A average forward current up to 100°C case temperature.

FAQ

What is the maximum junction temperature rating for GP1601H?

The GP1601H has a maximum junction temperature (T_J) of +150°C and a minimum of -55°C, enabling operation in under-hood automotive environments and industrial enclosures without additional derating below 16A at case temperatures up to 100°C. This rating is validated per AEC-Q101 stress testing protocols and confirmed in the GP1601H datasheet absolute maximum ratings table.

Is GP1601H pin-compatible with other GP16xx series rectifiers?

Yes, all GP16xx devices including GP1601H share identical TO-220AB package dimensions, pinout, and terminal assignments - Anode (Lead 1), Cathode (Lead 2), and Cathode-connected tab. Voltage variants differ only in internal die structure; mechanical and PCB footprint compatibility is maintained across the GP1601–GP1607 family.

Does GP1601H require a heatsink in 16A continuous operation?

Yes, GP1601H requires a heatsink for 16A continuous conduction. With 1.5°C/W R_θJC and ~17.6W typical power dissipation (16A × 1.1V), even a modest 10°C/W heatsink yields ~17.6°C rise above ambient - exceeding safe junction limits without thermal management. The TO-220AB tab must be mounted to a heatsink using ≤0.56 N·m torque and appropriate thermal interface material.

What does the "H" suffix signify in GP1601H?

The "H" suffix in GP1601H explicitly denotes AEC-Q101 qualification per the ordering information section of the GP1601–GP1607 datasheet. This certification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and high-temperature reverse bias (HTRB), confirming suitability for automotive power electronics applications.

How does GP1601H compare to Schottky rectifiers at 16A/50V?

GP1601H is a standard recovery rectifier with 1.1V VF and 10 µA IR, whereas Schottky alternatives (e.g., SB1650) offer lower VF (~0.55V) but higher IR (>100 µA at 125°C) and limited VRRM (<50V). GP1601H provides superior reverse blocking margin, thermal stability, and AEC-Q101 validation - making it more suitable than Schottky for automotive 50V systems where leakage and reliability outweigh minor conduction loss savings.
